' Tami-FURNACE.

Specification of Letters Patent.

Application filed August 4:, 1914, Serial No. 855,008.

To all whom it may concern:

Be it known that I, Gnonon YEAGER, a citizen ofthe United States,residing at Bay City, in the county of Matagorda and State of Texas,have invented certain new and useful Improvements in Tank-Furnaces, ofwhich the following is a specification.

This invention relates to water heaters, and more particularly to afurnace which is particularly adapted for use in connection therewith,and also relates to an improvement in a tank which is adapted for use inconnection with the furnace.

The object'of my invention is to provide a water heater as abovedescribedwhich is adapted to receive a water tank upon the furnacestructure thereof, and heat the water in the tank.

Another object of my invention is to provide a device of this characterwhich may be used in the open air and which is par-' ticularly adaptedfor use as a camp Water heater.

A still further object of my invention is to provide a water heaterwhich has a simple' and eifective means associated therewith forfacilitating a rapid heating of the.

water in a tank.

A still further object of my invention is to provide means forpreventing the contents of the tank from becoming burned, due to contactwith the bottom thereof.

My invention resides in the construction, combination and arrangement ofparts as more fully set forth hereinafter in the specification andillustrated in the accompanying drawings, in which :--v

Figure 1 is a side elevation of a water heater in which the preferredembodiment of my invention is illustrated.

Fig. 2 is a longitudinal sectional view of the same, and

Fig. 3 is a detail section on line 3-3 of Fig. 2.

Similar reference characters indicate similar parts throughout thevarious views of the drawings.

Referring more particularly to the draw-' or a cooking utensil issupported upon a topf opening of the base or furnace 1, a ledge or shelf3 bei ng provided upon the upper marginal edge of the said base 1 andthe tank 2 adapted to be seated or placed thereon. A transverse rod 3'extends across the furnace substantially intermediate its ends for thepurpose of preventing expansion of the same when a fire is startedtherein. A band 4 is secured to the outer surface of the furnace 1 bybolts or other suitable means 4' as is shown'to advantage in Figs. 1 and2. The band, at the point at which it enas to conform to the slantingsides of said furnace 1, the upper portion of said band 4 being verticalfor engagement with the base of the tank 2, said band 1 extendingslightly above the ledge 3, to provide a means for preventing lateraldisplacement of the tank;

- ucts of combustion are carried ofl from the furnace through a chimney7 extending from one end of said furnace 1.

The tank 2 is provided with a cover 8 or other suitable closure, and aprotecting plate .9 is provided in the interior of the tank 2 andsupported in spaced relation to the bottom 2 of said tank 2 by means ofthe downturned edge 10 thereof. The protecting plate 9 is similar inconfiguration to the tank 2 and is arrangedto fit snugly within the tankas shown in Fig. 2. Openings 11 gages the furnace 1, is flared outwardlyso 2 in :the plate 9 allow the liquid in thetank to circulate over andunder the plate 9.

The tank 2 is provided with a longitudinally extending conduit 12, saidconduit 12 being in communication with the chimney 7 by means of adownwardly extending tubular portion 13 whereby to receive the productsof combustion from the chimney of the furnace 1 and convey the samethrough the conduit 12 and out through the chimney portion 14 thereof,this conduit 12 provid ing an additional means for heating the, contentsof the tank 2.

As is shown to advantage in Fig. 2 the protecting plate 9 rests upon theconduit 12, 1

said conduit 12 serving as a means for supporting the central portion ofsaid plate, and preventing the bending of the same, as well as servingas a means for facilitating the heating of the water in the tank. FromFig. 2 the course of the products ofcombus tion and heat will be readilynoted, as the chimney 7 is connected with the furnace 1 and communicatestherewith by means of a tubular member 7', and the products ofcombustion leave the furnace 1 by the tubular member 7', passing upthrough the tubular connection 13 to the conduit 12, through which theheat and products of combustion will pass to the outer end thereof andthrough the chimney portion 14: to the outside atmosphere. The bottom 2of the tank 2, as will be readily seen from Fig. 2, is exposed to thefull heat of the furnace 1, and the smoke and other products ofcombustion pass through the conduit 12 and assist the main portion ofthe furnace in heating the water or other liquid in the tank 2.

When it is desired to boil the water in the tank a fire is started inthe furnace 1 and in a short while it will be found that the Water hasbeen brought up to the boiling point. The protecting plate 9 willprotect any articles which are in the tank 2, as in the case of a Washboiler the clothes which would be in the tank, from burning, due tocontactwith the bottom 2 of the tank 3.

The door 5 in the furnace 1 allows of easy accessto the interior of thefurnace l and the openings 6 below the door 5 pro: vide draft openingswith which to supply oxygen to the fire.

From the above it is thought that it will be readily appreciated that-Ihave provided a simple, cheap and durable furnace for heating water in atank, it being readily seen that the type of tank used is notnecessarily of the type which I have shown in the drawings as anyordinary wash boiler or tank which is the correct size will fit heopening in the top of the furnace 1, how- 1 ever, it is preferable thatthe tank should be made in the form which I have illustrated in thedrawings as it is found that this is a very advantageous structure whenused in connection with my improved furnace. The portions 13 and 7 arereadily detachable so that the tank and the furnace may be readilydetached one from the other to allow of emptying the tank or for movingthe same from place to place.

While I have shown a specific form of construction for my invention, itwill be readily understood by those skilled in the art that certainminor changes in the details of construction thereof may be made without departing from the spirit and scope of the invention hereinafterclaimed.

Having thus described my invention, what I claim and desire to secure byLetters Patent is In a combined furnace structure and tank, an outletfor the furnace extending :exteriorly thereof below the bottom of thetank, a conduit in the tank in spaced relation to the bottom thereof,said conduit having a right angular extension downwardly projecting fordetachable engagement with the furnace outlet, and means for preventingaccidental lateral displacement of said tank from said furnace, saidconduit serv ing to conduct the products of combustion from the furnacethrough the tank to heat the contents thereof.

In testimony whereof I ailix my signature in presence of two witnesses.
